An integrated sensor for the measurement and monitoring of position and inclination, characterized by low cost, small size and low weight, has been designed, realized and calibrated at the Geomatics Lab of the University of Calabria. The design of the prototype, devoted to the monitoring of landslides and structures, was aiming at realizing a fully automated monitoring instrument, able to send the data acquired periodically or upon request by a control center through a bidirectional transmission protocol. The sensor can be released with different accuracy and range of measurement, by choosing bubble vials with different characteristics. The instrument is provided with a computer, which can be programmed so as to independently perform the processing of the data collected by a single sensor or a by a sensor network, and to transmit, consequently, alert signals if the thresholds determined by the monitoring center are exceeded. The bidirectional transmission also allows the users to vary the set of the monitoring parameters (time of acquisition, duration of satellite acquisitions, thresholds for the observed data). In the paper, hardware and software of the sensor are described, along with the calibration, the results of laboratory tests and of the first in field acquisitions.

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver condition characterized by excessive hepatic fat accumulation. Early diagnosis is crucial as NAFLD can progress to more severe conditions like steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma without timely intervention. While liver biopsy remains the gold standard for NAFLD assessment, abdominal ultrasound (US) imaging has emerged as a widely adopted non-invasive modality due to convenience and low cost.

Brain tumours are one of the most deadly and noticeable types of cancer, affecting both children and adults. One of the major drawbacks in brain tumour identification is the late diagnosis and high cost of brain tumour-detecting devices. Most existing approaches use ML algorithms to address problems, but they have drawbacks such as low accuracy, high loss, and high computing cost.

Purpose: The priorities and concerns of sarcoidosis patients in the United States (US) have not been well-described.
Methods: A survey constructed by sarcoidosis patients and doctors was administered to US sarcoidosis patients. The survey queried patients concerning their demographics, disease state, disease impact on health and well-being, health care priorities and impressions of sarcoidosis care.

A novel whispering-gallery mode (WGM) sensor is fabricated by coupling a tapered two-mode fiber and a glass capillary. By utilizing the relatively large orifice of glass capillaries, polydimethylsiloxane (PDMS) and magnetic fluid are directly injected into two WGM structured glass capillaries, respectively, allowing these materials to substantially interact with the light field of the WGM, thereby achieving temperature, pressure, and magnetic field measurements. λ1 and λ2 are the two resonant peak wavelengths of the WGM after injecting PDMS into a glass capillary.

Background: Low participation in cancer screening contributes to a disproportionate burden of cancer morbidity and mortality among adults with mental health (MH) disorders like depression and anxiety. It is unknown whether MH treatment affects screening participation in this population.
Methods: Using the 2019 and 2021 National Health Interview Survey, data from screening-eligible respondents with a history of depression or anxiety were analyzed.
